RbPSe - Sony PlayStation (PSX) emulator.
RbPSe is written entirely in assembler. It uses dynamic recompilation for processor emulation which is one of the fastest ways. In order to emulate graphic, sound and CDROM subsystems you'll need to use PSEmuPro plugins.
It allows emulator to work with almost any hardware. HLE (High Level Emulation) emulation allows to significantly increase emulation speed by replacing PSX BIOS calls by similar PC functions.
